Dementia with Lewy bodies (DLB) is an increasingly common form of progressive dementia that affects the brain. It is estimated that DLB affects approximately 1.4 million people in the United States. The condition is associated with an affected person's ability to think, remember, and reason, and can cause a range of physical and behavioral symptoms. As with any form of dementia, the progression of the condition varies widely from person to person.
In general, the prognosis for people with DLB is poorer than for other forms of dementia. People with DLB typically live for an average of 3-8 years after diagnosis, although some may live for longer. As the disease progresses, the affected person may experience a decline in mental and physical abilities. This may include memory loss, difficulty with motor coordination, and changes in behavior.
As the disease progresses, the person may require more and more assistance with activities of daily living. This assistance may include help with eating, dressing, bathing, and toileting. In addition, the person may also need help with managing money, medications, and transportation.
Although there is no known cure for DLB, treatments can help to slow the progression of the disease and improve quality of life. These treatments may include medications, occupational therapy, speech therapy, physical therapy, and counseling.
Ultimately, the length of time a person can live with DLB depends on a range of factors, including the severity of the condition, the person's overall health, and the level of care they receive. With proper care and support, it is possible for people with DLB to live longer than the average prognosis.
